IMPROVEMENT IN SIPHON STEAM-PUMPS.

Specification forming part of Letters Patent No. 153,378, dated July 21, 1374; application filed March 14, 1874.

To all whom it may concern:

Be it known that 1, CHARLES ROGERS, of the city and county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Siphon Steam.- Pumps; and I do hereby declare that the following is a full, clear, and complete description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to an improvement in siphon steam-pumps; and consists of a shell provided with a cylinder, the bore of which is contracted between its inlet and outlet, the said shell also having a steam chamber furnished with a series of small discharge-pipes, surrounding a center-piece, which, with the said pipes, is held concentric to the bore of the said cylinder through the medium of a flanged disk.

To enable others skilled in the art to which it pertains to make and use my invention, 1 will proceed to describe its construction and operation.

In the accompanyingdrawings, which form part of my specification, Figure l. is a side elevation of my improvement in siphon steampumps. Fig. 2 is a vertical section of the same. Fig. 3 is a vertical and transverse section of the same at line 3 of Fig. 1.

In the accompanying drawings, A represents the shell, having a cylinder, B, which is contracted at U, a point about midway between its inlet 1) and its outlet 6, the bore of which is about equal to the bore of the dischargepipe attached to the shell A atf. To the shell A is attached a steain-chamber, g, consisting of the parts It and t'. Thepart h is furnished with a series of stean1-pipes,j, surrounding a centerpiece, k, the contour of which corresponds to the bore of the cylinder B, the said pipes and center piece being arranged concentric to the axis of the cylinder B. The part6 of the steam-chamber g is secured to the part It through the medium ot' screws or bolts, as indicated at l. The pipesj and center-piece k are held in position with relation to the bore of the cylinder B through the medinmot' flanged disk m, the interior of which, to prevent condensation of the steam in pipes j by cold water or other fluid, is packed with any suitable material, preference being given to asbestus. The steam-supply pipe r is attached to the part a, as indicated at a, and the pipe 8, through which the liquid is drawn up into the shell A, is attached as indicated at 0, and the discharge-pipe t, which conveys the liquid off to the place desired, is attached to the shell, as indicated at f.

By constructing the siphon steam-pump as hereinbefore described, the space between the inner wall of the cylinder B and the cent-erp'iece It being narrow and contracted, the steam, rushing into the cylinder B in jets through the pipesj, will be rapidly condensed by the cold water or other liquid coming into contact with the outer wall of the cylinder B, and the condensation of the steam will form a vacuum in the cylinder, which will give power and force to the action of the pump, whereby the liquid will readily flow with force through the pipe s into the shell A, and, passing through the cylinder B, will be discharged with great rapidity through the pipe t attached to it.

The efiicieucy oi the siphon steampump depends on the rapidity of the condensation of the steam, and it will be readily observed that by the arrangement of the parts hereinbefore described a sudden condensation of the steam will be efl'ected, and therefore an increase of the power and efliciency of the pump will be the result.

Having thus described my improvement, what I claim as of my invention is- In a siphon steam-pump, the shell A, provided with a cylinder, B, contracted at or near the center of its bore, in combination with the center-piece k and steam jet pipes j surrounding it, substantially as herein described, and for the purpose set forth.

CHAS. ROGERS.
